Be it known that I, HARVEY V E'IIGLEY a citizen of the United States,owl resident of Detroi'i; VJe iie county Stale Michigan, have iiiveitecl certain new and useful Improvements in Gas-Measuring Appomtus, ofwhich the following is a specification.

The present invention relates to gas measuring apparatus and moreparticuloi ly to an apparatus for accurately measuring out volzones, 2 aThe-apparatus has been clevised particularly for measuring volumes ofsulfur clioxid to be tested for purity and content, although, as Willbeappei'en'l; it is not limited to this use. 4

The prinoipel features of lime invention consist in the provision ofmeans for cleliv Qiiligf volume of Whichlieve been measvicli emeoccuracy; in she pro; vision of means closely adjacent the meesui in};means for determining the temperature and. pressure of'the gas; in theprovision of an oppomius-which is free from pockets which mightinterfere with accuracy of the measuring; in the provision of an;apparatus of the type'mentionell constructed and ar rengecl to deliverall the gas'measur eci and in the provision of an apparatus Wliich iseasily manipulated. StilBI features and objects will be apparent fromilie description iaken in connection with the olrewings in Whici 2' e le. frontelevetioii of on opporaitvs constructed in accosfieoce with thepresent invention; v Y

At theother c0r1ier,' the upper. right hand corner of Fig. 1, the from v boardhas e pin 16 which is'odaplced to o l-{1Q gage in any one ofelie threerecesses-1'? formed in the buck board As Shown the front board carries aspacing sleeve 18 which slides on the wear plate 19 carried by "the 6back board, and e soringQO within the sleeve acts against av collar 21securedio the pin 1,6 to force the latter? into oneof the recesses. Itwill be seen that the recesses 17 are s j ranged so that when the pin 16is in the central one the from; board is horizontal and? when in eitherone of the end-recesses '17 the i;- saidboard is tilted to the left orthe'riglit accordio to which hole the pin engages. The parts of theapparatus-Which are used for measuring the gas are secured in anysuitable manner so the front side of the board 13.'
